maintain in a closed position a pair of doors.

which are disposed. within the frame of a single doorway, and the ob ect of my improvement is to provide a strong and simply constructed latch that shall unite and se-. curely hold in a closed position the two' doors of pair of doors mounted in a single door frame, as, for instance, the pair of doors that is employed to close therear end of a covered delivery wagon such as employed by mercantile houses for the delivery of merchandise an'd'a further object of my improvement to hold such pair of doors in such tightly closed position as will eiieo tively prevent a rattling or vibration of the doors irrespective of any wear of the latch orloosencss of its parts. I accomplish these objects by devices illustrated in the accompanying drawings in which-- Figure-1 is a view in front elevation of my latch as it appears when latched, Fig; 2, is a plan view, on a reduced scale, of the same when associated with a pair of doors and asit may appear when it is unlatched; Fig. 3, is a plan view of the same showing the parts in a latched position and Fig. 4C, is a view in perspective of a detail of my invention.

Referring to-the drawings, in which like reference numerals indicate like parts, 5 and 6 indicate a pair ot-doors which may be hinged at their outer side edges and adapted to close, as illustrated in Figs. 2 and 3,

against any suitable stop as a door frame or a block 7.

A fiat strip 8, of suitable metal, as spring steel, is formed tohave its two end portions lie in planes thataTe at a slight angle to each other, as more clearly illustrated in Fig. 1, one of such end portions being provided with holes 9, 9 through which rivets or bolts 10 and 11 respectively, may extend to secure said strip 8 to a door, as illustrated in Fig. 2, the bolt 11 being formed with a head or lug 12 which is disposed to project outwardly from the outer surface of the itlllp and which lug 12 is provided with a A flatbar 14 is provided with an enlarged perforated end portion 15 by which said bar 14 is hinged to a Ushaped bolt bracket 16 which pivotally secures'the bar 14 to the door .6, as illustrated in Figs. 2 and 3, such bar 14 being provided at its other end with a slot 17 that is adapted to fit over the lug 12 of the bolt 11.

A hook shaped member 18 is pivotally secured to the bar 14 by a rivet or bolt 19 and is adapted freely to be turned in a plane that is parallel with the bar 14, such hook 18 being provided with a handle 20 by which it may be turned and being adapted to have its outer hook shaped end thrust through the 1 perforation 13 in the lug 12 of the bolt 11,

as illustrated in Figs. 1 and 3, to fasten securely the doors 5 and 6 in Fig. 3.

A hole 21 is provided in the extreme end portion of the hook 18ywhereby a padlock together, as shown may be attached to lock the latch in its closed position.

The bar 14 which is hinged to the door 6 by the U shaped bolt 16 is adapted freely to swing outwardly to permit the doors 5 and 6 to be opened and the bar 8-is rigidly se cured to the door 5 by the bolts 10 and 11, the free end portion of such bar 8 normally lyin in a plane that is at an angle to the plane of the doors 5 and 6, as illustrated in Fig. 2, to adapt su'ch bar 8 to act as a spring.

In the operation of closing the doors 5 and 6, the door 6 is first closed and then the door 5 is closed and thereupon the bar 8 will overlap the dcpr 6. The bar 14 is then swung into the position shown in Fig. 2, in

which position such bar 14 will engage with the end of the bar 8 and then a continued inward movement of the bar 14 will overcome the spring force of the bar 8 thus tending to straighten such bar 8 as illustrated in Fig. 3, wherein the bar 14 is shown to be pressed tightly against the bar 8 and there secured by hook 19 which projects its hooked end downwardly through the hole, 13 in the lug 12.

Obviously the spring like bar 8 exerts a constant pressure against the b'an 14 and serves to eep the doors tightly closed and to prevent any rattling of the doors and the parts of the latch.

When the doors are to be opened the handle 20 may be grasped and pressure may be exerted thereon to press the member 14 inwardly and at the same time a lifting or twistin force is exerted to raise the hook 18 upwar ly ,into a position as shown by broken lines in Fig. 1, as soon as the hook 18 is free from the lug 12 the bar 8 will spring outwardly into the position shown in Fig. 2 and the bar 14 may be swung backwardly to ermit the doors freely to open.

If it be esired to use my late in connection with a single door the bar 14 may be hinged to the door frame, in the samemanner that such bar 14 is hinged to the door 6, thus, it is manifest that my latch is adapted to be used in connection with either single or double doors and, obviously, changes may be made in forms and dimensions of its several parts without departing from the spirit of m invention;

W at I claim is:

1. A door latch comprising a latch-bar adapted to be pivotally secured at one end to a support and provided at its other end with an opening, a hasp-hook pivot-ally secured to said latch-bar to swingingly turn thereon, of an, eye-bolt whose eye portion is adapted to project through said opening to engage with and be secured by said hasphook, a fiat spring adapted to be associated with said eye-bolt and to be disposed so that one of its ends may engage with and press against the pivoted end portion of said latch-bar.

2. A door latch comprising a latch bar adapted to be pivotally secured at one end to a support, a spring member secured to another support'and disposed so that one portion of it may engage with and press against the inner surface of said latch bar and means for releasably securing the free end of said latch bar to said last named support.

In witness whereof, I, hereunto subscribe my name this 1st day of December A. D., 1913.
